Which outcome increases risk during nuclear reactor startup?

💡 Explanation

Uncontrolled reactor startup risks neutron flux increases, because iodine-135 builds-up, then decays to Xenon-135. Therefore, neutron absorption increases and damps, rather than decreases; different isotopes mitigate the risk under controlled Ramp-Up conditions because of operator interventions.
